Abstract: A method for manufacturing CZTS nanoparticles and CZTS nanoparticles manufactured by the same are provided. The method for manufacturing CZTS nanoparticles includes a step of preparing a precursor solution by mixing water-soluble salts containing Cu, Zn, Sn and S and water, and a step of synthesizing CZTS nanoparticles through the reaction of the precursor solution at a certain temperature. In the method, the CZTS nanoparticles may be manufactured without using a poisonous material and the method is eco-friendly. Since the CZTS nanoparticles may be manufactured by a hydrothermal synthesis using water as a solvent, the CZTS nanoparticles having high quality may be manufactured at low cost. Further, since the CZTS nanoparticles may be used as a replacing material of a common CIGS thin film solar cell, a solar cell having high efficiency may be realized at low cost.

Abstract: The present invention relates to a solar cell including a fluorescent substance and a manufacturing method thereof. The solar cell including a fluorescent substance includes a rear side electrode, an optical absorption layer, a buffer layer, a window layer and a front side electrode laminated in serial order. The optical absorption layer includes fluorescent substance at a steady rate so that the photocurrent density is increased, and photoelectric transformation efficiency of the solar cell is improved. Meanwhile, the manufacturing method of solar cell including fluorescent substance comprises the following steps: forming a back side electrode on the substrate; forming the optical absorption layer including fluorescent substrate on the back side electrode; forming the buffer layer on the optical absorption layer; forming the window layer on the buffer layer; and forming the front side electrode on the window layer. Therefore, a separate layer including a fluorescent substance does not need to be arranged. With a simple method of including a fluorescent substance directly in the optical absorption layer, the photoelectric transformation efficiency of the solar cell can be improved.
